The staff in the mathematical sciences at Plymouth University have a number of different components to their job descriptions. It is obviously important to be an excellent teacher, but another part of the job description is maintaining international leadership in a research field. There are other hidden part of the job too , such as administration.
If external support can be found, staff can take a sabbatical, typically for a year, at another institution, so that can concentrate on their research. Dr. Antonio Rago from CMS is visiting CERN for the year 2017-2018 to work on research full time. He is working in the theory division of CERN.
